Growing Tips for Critical Jack Auto
Critical Jack Autoflowering cannabis is an easy-to-grow strain that is preferred by novice growers. Critical Jack Auto marijuana plants will thrive indoors and outdoors, but have an easier time growing indoors because of the ability to completely control the climate. If you choose to grow indoors, you will have to replicate a steady environment similar to a warm, temperate climate. Critical Jack Auto cannabis seeds grow bright green plants with yellow pistils and resinous trichomes covering the bud sites so much that the buds appear yellow. If you choose to grow outdoors, you will need consistent temperature and humidity to grow these plants to completion. Doing so will ensure that you grow healthy buds from the top of the plants to the buds closest to the soil. Having access to a greenhouse is the best way to give these plants the perfect outdoor climate without having to contend with unexpected outdoor variables — a particularly useful option for growers in Canada's cooler regions. These plants grow to a medium height and can reach around 90–150 centimetres tall. Because the plants reach a maximum indoor and outdoor height of approximately 150 centimetres, they will need to be trimmed so they continue to fit in your grow area. The ideal temperature for these plants is around 21–26 degrees Celsius and slightly cooler at night. Humidity levels should be kept around 40–60% during the vegetative growth stage and the flowering stage, but lowering the humidity every week will help this plant grow. Growing indoors will ensure that moderate humidity levels and moderate temperatures are constant and maintained every day that the plants are in the growing stages. Pruning and low-stress training (LST) methods will help these plants grow correctly. Each method will help the plants maintain the desired shape and height. The Critical Jack Auto strain requires an 18-hour light cycle to reach the vegetative stage of growth. You do not need to change the light cycle to induce the flowering phase of growth.
Yields, Flowering Time, and Harvest
- Flowering Time: Growing indoors, you can expect the Critical Jack Auto strain to harvest after a short flowering period of 50-60 days.
- Yields: Indoor yields are around 500 grams per square metre, while outdoor grows typically produce up to 800 grams per plant. These yields are absolutely massive and will keep the grower flush with buds for a long time after harvest.
- Harvest: Outdoor growers in Canada can plan on harvesting their yields around the beginning of October, depending on when the seeds were planted.
